From b2e3e4fa3eee752b893687783f2a427106c93423 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Tue, 5 Apr 2011 00:23:57 +0200 Subject: [PATCH] x86-32, numa: Make pgdat allocation use alloc_remap() pgdat allocation is handled differnetly from other remap allocations - it's reserved during initialization. There's no reason to handle this any differnetly. Remap allocator is initialized for every node and if init failed the allocation will fail and pgdat allocation can fall back to generic code like anyone else. Remove special init-time pgdat reservation and make allocate_pgdat() use alloc_remap() like everyone else.
